14. Bar Graph b The purpose of a bar graph is to display and compare data. b Bar graphs use bars to show the data. b A bar graph must include: - a title - a title - labeled X and Y axes - labeled X and Y axes - equal intervals are used on the Y axis - the bars are evenly spaced apart from each other Return to Graph

15. Stem and Leaf Plot b Stem and leaf plots are used as a quick way of seeing how many pieces of data fall in various ranges. The reader can quickly tell: - the range - the range - the mode - the mode b Stem and leaf plots have a title, a stem, and leaves b A key is used to explain how to read the stem and leaves. Return to Graph

16. Pictograph b All pictographs have a title. b Rows and columns shape the pictograph. b Label each row and column. b Use pictures to show the data. b Each picture equals a certain amount of data. b Pictographs need a key. Return to Graph

17. Line Graph b A line graph is used to illustrate change over time. b Line graphs need: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal Intervals - Equal Intervals - Data displayed by points connected into lines Return to Graph

18. Double Line Graph b A double line graph is used to compare two groups of related data over time. b Double line graphs need: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal Intervals - Data displayed by points connected into lines - Key Return to Graph

19. Circle Graph b Circle graphs are used to display parts of the data in relation to the entire amount of data. b All circle graphs need a title. b Each part is called a sector and is labeled. b All angles correct (+2/-2 degrees) Return to Graph

20. Double Bar Graph b The purpose of a double bar graph is to compare two or more sets of data. b Uses bars to show the data. b Double bar graphs must include: - Title - Title - Labeled X and Y axes - Labeled X and Y axes - Equal intervals are used on the Y axis - Pairs of bars are equally spaced, but the compared bars are not - Key Return to Graph

21. Line Plot b A line plot shows the spread of all the data on a number line. b Easily identifies the mode. b All line plots include: - a title - a title - a numbered horizontal line - a numbered horizontal line - data displayed by use of X’s - data displayed by use of X’s Return to Graph

22. Histogram b Histograms are used to show the frequency of data. b Very similar to bar graphs, but use intervals on the X axis. b Bars do touch. b Histograms have a title. b Histograms have two axes which are labeled. Return to Graph

23. Box - and - Whisker Plot b Displays large set of data. b Gives general idea of how data clusters. b Graph includes: - Title - Title - Labeled intervals - Box between lower and upper quartiles - Whiskers from quartiles to extremes - Median, quartiles and whiskers labeled Return to Graph

24. Scatter Plot b Shows how closely two sets of data are related b The closer the sets are related, the closer the points come to forming a straight line. b Scatter Plots include: - title - labeled axes - equal intervals - corresponding numbers plotted as ordered pairs Return to Graph

25. Stem-and- Leaf Plots Stem-and- Leaf Plots b A stem-and-leaf plot shows numerical data in an organized chart b The “stem” is the tens digit and everything above. “Stems” cannot be repeated b The “leaf” is the ones digit. “Leafs” CAN repeat. If you have multiple leafs under a steam, use a comma to separate them b Create a stem-and-leaf plot using the following data 28, 120, 56, 30, 123, 29, 40, 41, 43 StemLeaf 28, 9 30 40, 1. 3 56 120, 3
